Frequently Asked Questions
Do I need clamps to install this hose?
Yes. You'll need clamps on both the inlet and outlet ends. Hose clamps are sold separately — use stainless steel clamps rated for your application (coolant, vacuum, or boost).
Can I use this for pressurized coolant lines?
The 3-ply construction is rated for moderate pressure and boost applications. For high-pressure coolant systems, confirm your system's PSI rating against silicone hose specifications before installation.
Does this need any prep before connecting to hard lines or other hoses?
Clean the connecting surfaces of any debris or old clamp residue. The hose is ready to use straight out of the bag — no priming or treatment required.
